Let’s start off our tour of this year’s honorees with Spartacus Chetwynd, a 38-year-old female artist who changed her name from Lali when she turned 33, because, according to the BBC, she wanted “to remind people they have a choice in life.”

Chetwynd specializes in performance art, featuring home-made costumes and audience participation. She is shortlisted for her work Odd Man Out, showing at the Sadie Coles HQ gallery, which involves puppeteers, a mime and a giant inflatable slide. According to the gallery:

The five-hour performances revolve around ideas of democracy, the right to vote and the disincentives against engaging in politics. Giant photocopies work as barriers to divide the gallery into alternative routes, with voting booths at the start of the exhibition leading through to different performances. Be careful who you vote for in Odd Man Out as your vote has a literal effect on the outcome of your circumstance.
